$erial No. 712,967- (No model.)

- trolling the supply of liquid to a filter or other receptacle; and it consists in means by which an accumulation of the liquid to be delivered is caused to take place, which accumulation may continue until the liquid so accumulated is sufiicient to fill a filter or other receptacle, whereby a rapid filling of the latter is obtained instead of the gradual filling which would otherwise take place.

Our invention is illustrated in the accompanying drawings, in which- Figure 1 is a longitudinal section, and Fig. 2 a plan view, illustrating one method of carrying out our invention, a pair of siphons and a tipping diverter being employed. Fig. 3 is a longitudinal section, and Fig.4 a plan view, of another method of carrying out our invention and in which a single siphon is employed through which the liquid is delivered. Fig. 5 is a longitudinal section, and Fig. 6 a plan view, of a modified arrangement in which a tipping bucket controls the delivery of the liquid.

In carrying out our invention, as shown in Figs. 1 and 2, we arrange a pair of siphons 2 and 3 in such a position in connection with the receptacle 1 in which" the sewage or other liquid accumulates that when the level of such liquid reaches a certain height in such receptacle it will overflow through either of same. The outer ends of the siphons dip into the liquid contained in a tipping diverter 4, over the edges of which such liquid can pass into distributing-channels 7 and 8, delivering the liquid respectively to the filters 5 and 6. This diverter is actuated in any suitable manner to deliver the liquid to either of such chan nels-such, for instance, as the pair of buckets 30 31, mounted on a frame secured to the shaft 34, on which the diverter is also secured, the buckets being operated by a portion of the liquid from the filter5 or 6 flowing through the overflow-pipe 32 or as soon as the filter being supplied is full.

In order to stop the flow through either-siphon on the filling of one of the filters, we may arrange a valve 35 at the upper end of each siphon, the valve, being carried by'levers 36, to the ends of which rods 37 are secured,which extend downward and are adapted to be lifted on the diverter being actuated, thereby lifting the valve andso admitting air to the siphon and stopping its action.

In the positions shown in Figs. 1 and 2 liquid is flowing through the siphon 3 into the diverter 4 and thence into channel 8, from which it passes into the filter or receptacle 6. As soon as the latter is full a portion of its contents will overflow through overflow-pipe 33 into bucket 31, thus depressing the latter and so changing the position of the diverter 4, and this movement will lift the rod 37, 9.0- tuating the valve 35 of siphon 3, and so admit air to the latter and stop its action, while at the same time the valve 35 of siphon 2 will close by its weight. The sewage or other liquid will then commence to accumulate again in the receptacle 1 until it reaches the height necessary to charge the other siphon 2, the valve 35 of which is closed, when this siphon will be brought into action, and the abovedescribed operations will be repeated.

In the arrangement shown in Figs. 3 and 4 it will be seen that the sewage or other liquid accumulating in the tank or receptacle 1 passes therefrom through a siphon 2 into a chamber in which valves 21 and 22, opening 0 into passages 38 and 39, leading, respectively, to the two filters 5 and 6, are placed. The opening and closing of the valves 21 and 22 may be effected in any suitable manner; but we prefer the arrangement shown, which consists in mounting them on a lever 23, secured to a shaft 34, actuated by a pair of buckets 3O 31, mounted on a suitable frame and which oscillate the shaft when one or the other of such buckets is filled by the overflow from too one of the filters or receptacles 5 6, such overfiow passing through pipe 32 or 33 when the filter or receptacle is filled.

In order to allow the liquid in the receptacle 1 to accumulate, so that the filling of the filters may take place rapidly, we arrange the siphon 2 at a suitable height in relation to the receptacle 1, so that sufficient liquid will have accumulated to fill a filter by the time the level in such receptacle reaches such a height in the siphon that the latter will be fully charged and so brought into action, and we provide suitable means by which the flow through such siphon will be stopped when the filter is full. This we prefer to effect by admitting air at the top of the siphon 2 through a valve, such as that shown at 35, and which is lifted by any suitable means on the filling of the filter. The means shown in the draw- ,ings consist of an arm mounted on the shaft 34 of the buckets 3O 31 and to which is pivotally connected a rod 36, passing through an extension of the valve and provided with a cam-surface 37, which acts on such extension and so lifts the valve slightly on each movement of the buckets 3O 31 in either direction. Air will thus be admitted into the upper end of the siphon and so immediately stop its action.

In the position shown in the drawings bucket 31 has just been depressed, thus opening valve 21 and closing valve 22, so that the sewage or other liquid in receptacle 1 is passing from receptacle 1 into filter 5. As soon as filter 5 is filled a portion of the contents of its collecting-well will overflow through pipe 32, thus depressing bucket 30 and closing valve 21 and opening valve 22 and at the same time drawing the cam-surface 37 through the extension on the siphon air-valve 35, raising the latter, and so admitting air to the siphon and stopping the flow therethrough. As above stated, the valve 22 will be opened by this movement of the buckets 30 31; but the filter 6, supplied by this valve, Will not be filled until a sufficient quantity of liquid has again accumulated in receptacle 1 to fully charge and so bring the siphon 2 into action.

According to the modification of our invention (shown in Figs. 5 and 6) the supply of sewage or other liquid from the receptacle 1 is controlled by means of a tipping bucket 50. An overflow-pipe 52 is so arranged as to deliver liquid into this bucket from the receptacle 1 when it reaches the desired height in the latter, so that the bucket when filled will be tipped on its pivot and being connected by lever 56 with the valve 5: will open the latter and so cause the filling of one of the filters or receptacles 5 or 6, the admission of the liquid to either of these being preferably controlled by valves 21 22, carried by a lever 23, mounted on the shaft 34:, on which shaft a frame carrying a pair of buckets 30 31 is also mounted. These buckets are operated by overflows from the collecting-wells of the filters or receptacles 5 and 6, such overflow passing through the pipe 32 or 33 when the filter or receptacle 5 or 6 is filled.

The liquid escapes from the bucket 50 after the latter has been tipped through a small hole provided for the purpose; but such bucket is retained in its tipped position during the filling of a filter by means of any suit able catch operated by the alternating gear and which will be released from the bucket as soon as the filter is full, thereby allowing such bucket to return to its normal position and the valve 54 with which it is connected to close.

As above stated, any suitable form of catch may be employed for retaining the bucket 50 in its tipped position during the filling of a filter, the arrangement shown for this purpose consistingin an arm 60, mounted on the shaft 34, carrying the buckets 30 31, and the end of which acts on one arm of a bell-crank lever 58, pivoted at 59, and the other arm of which forms the catch to hold the bucket 50 in its tipped position. It will be seen that when the buckets are actuated in either direction the arm will act on the end of the bell-crank lever and turn the latter slightly on its pivot 59, so that its other end will be removed from the path of the bucket 50, which will thus be able to return to its normal position and so close the valve 5i with which it is connected.

In the positions shown in thedrawings the filter or receptacle 5 is nearly filled, the bucket 50 having been tipped and being retained in its tipped position by catch 58, while the valve 21 is open and valve 22 closed. As soon as filter or receptacle 5 is filled a portion of its contents will overflow through pipe 32 into bucket 30 and so depress the latter, this movement turning the shaft 3t so that catch 58 will be released from bucket 50, and the latter will then resume its normal position and the valve 5 1 with which it is connected will be closed, thus cutting 01f the further supply of liquid from receptacle 1, which will not be resumed until sufficientliquid has accumulated in such receptacle 1 for a portion of same to again pass through overflow-pipe 52 into bucket 50, when the latter will be again tipped and will be retained in its tipped position until filter 6 has been filled.
